Abstract

A hydrodeoxygenation catalyst comprises a metal catalyst, an acid promoter, and a support. The metal catalyst is selected from platinum, palladium, ruthenium, rhenium rhodium, osmium, iridium, nickel, cobalt, molybdenum, copper, tin, or mixtures thereof. The support is a promoted-zirconium material including texture promoters and acid promoters. The hydrodeoxygenation catalyst may be used for hydrodeoxygenation (HDO) of sugar or sugar alcohol in an aqueous solution. In one embodiment the HDO catalyst may be used for HDO of fatty acids such as fatty acid methyl esters (FAME), triglycerols (in plant oil and animal fat), pyrolysis oil, or lignin. The hydrodeoxygenation catalyst for fatty acid process does not require the use of an acid promoter, it is optional.

Description

BACKGROUND

[0001] Compared to crude oil, biomass feedstocks have intrinsically high oxygen contents ranging from 6% for nature oil and fats to more than 50% for carbonhydrates. Conversion of these feedstocks to high value chemicals or “drop in” fuels without excessive sacrifice of carbon by decarboxylation / decarbonylation requires hydrodeoxygenation (HDO) as a mandatory process step. The HDO process is similar to the hydrotreating process which has been widely applied in petroleum refinery. It removes oxygen as “impurity” in the form of water by consumption of hydrogen.

[0002] Renewable diesels from HDO of plant oil and animal fats have been commercially produced by using conventional NiMo- and CoMo-based hydrotreating catalysts on zeolites or silica-alumina. The success can be attributed to the relatively low oxygen content, less impurities in the feedstocks, and importantly, the process design and optimization (U.S. Pat. No. 7,955,401, U.S. Publication No. 2010 / 0331586). These convent...
